UPDATE: Il Divo coming to the Straz Center in Tampa

Trivia time! What was the highest-grossing concert in the history of the Mahaffey Theater in St. Petersburg?

Give up? It was Il Divo, on June 28, 2009. The event raked in $208.119.10, all in one night. That is some BANK, holmes.

So snicker all you want at operatic pop artists like Josh Groban, Celtic Woman, Sarah Brightman and, yes, Il Divo. But the fact is those cats are so in demand they're packing arenas and giant theaters all over the globe, and people are paying out the nose to see them.

Want more proof of Il Divo's drawing power? The Simon Cowell-backed supergroup is headlining not one but TWO shows next summer at the Straz Center's Morsani Hall. According to promoter AEG Live and their own website, Il Divo have a two-night stand lined up at the Straz Center on June 15 and 16. (There's also a gig June 12 at the Bob Carr Performing Arts Centre in Orlando).
